Product Features & Applications
Product Feature:
- Adopt 8-inch touch screen, rich display content, easy operation.
- Ready to use after power on, no need to install weights.
- Electronic loading, closed-loop force control, high precision, to ensure the stability and repeatability of test results.
- Three methods of Brinell, Rockwell and Vickers hardness test.
- Automatic hardness conversion.
- Equipped with high-precision optical system, can clearly present the indentation to ensure the accuracy of measurement.
- With large storage space, it can store a large amount of measurement data, and can be easily retrieved and printed. Users can view historical test data at any time, conduct data analysis and comparison, and provide strong support for quality control and research work.
Product Application:
- Material research:
Used to evaluate the hardness characteristics of materials and provide data support for material selection, design and development.
- Production quality control:
During the manufacturing process, it is used to detect whether the hardness of the product meets the standard and ensure product quality.
- Failure analysis:
When equipment or parts fail, by analyzing the change in its hardness, the cause and mechanism of failure can be inferred.
